Keynote talk and introduction to QoSMOS project

Paul Jenkins, Head of Strategic Programme, BT

Paul Jenkins welcomed the attendees at the meeting and gave a brief introduction to BT and to the QoSMOS project. He emphasised the importance of wireless as a tool in the box for connectivity for broadband and the internet of things, and of sharing as an attractive option for finding more spectrum especially below 3GHz.

Michael Fitch presented an overview of QoSMOS, starting with the wireless landscape at the start of the project, giving the main results of the project and explaining where the project had influenced the landscape. The key results from the project can be grouped into architecture, enabling technologies and business modelling. The output of QoSMOS are the building blocks needed to provide technical and commercial realisation of spectrum sharing with QoS and mobility support. Contributions from QoSMOS to standards and engagement with industry and regulators through the External Advisory Board have increased the potential market size through improved alignment with regulators and other stakeholders although the situation remains non-uniform across Europe and more needs to be done possibly through trials.

QoSMOS technical briefings

Per H. Lehne, a senior researcher at Telenor, spoke about the use cases and business models used in the QoSMOS project. First he explained the process used to select the four use cases that QoSMOS would focus on. He then gave details on the business case analyses for two particular implementations of these use cases, using TV white space (TVWS) spectrum: Using TVWS for capacity extension of an LTE network and Cognitive femtocells to provide a mobile service. For each of these analyses Per highlighted the key parameters which can affect the potential success of each implementation. For the case of using TVWS for capacity extension of an LTE network the key parameter is the cost that an operator would have to pay to buy alternative spectrum, for the other implementations the key parameters are the number of subscribers and the average revenue that a subscriber is likely to pay.

Klaus Moessner (University of Surrey) presented QoS and Mobility Support in CRS the QoSMOS approach.

Professor Klaus Moessner, of the University of Surrey, gave a presentation on the mobility and QoS suport for cognitive radio. He gave details of how the QoSMOS system architecture has been designed to provide both mobility and QoS in a range of deployment scenarios. Klaus provided further details on the two-part cognitive manager design including results from investigations into the functionality of a spectrum manager. These investigations included opportunity modelling and the demonstration spectrum manager with a TVWS database.

Dominique Noguet, QoSMOS technical manager and Head of Wireless and Security Technology Dpt at CEA-LETI, gave a presentation on the physical layer radio technologies developed in the QoSMOS project, with a focus on filter bank multiple carrier (FBMC). Dominique explained how this new modultion method, which is also under discussion in IEEE DYSPAN 1900.7, allows for improved adjacent channel leakage ratios, frequency flexibility and also for pooling of spectrum which might be fragmented. He explained how this compares to OFDM and uses results from the TVWS demonstration to show how FBMC is much better suited to efficient usage of TVWS than OFDM.
